Spill Management

Firefighters should wear a National Institute for Occupational Safety and Health (NIOSH) approved self-contained breathing apparatus with a full face piece and protective clothing to prevent contact with skin and eyes. Use a water spray to cool fire-exposed containers. Do not spray water directly on the material. Accidental mixing with oxidizers like potassium chlorate, potassium nitrate, or potassium nitrite may result in an explosion hazard during fires. Sulfur oxides and ammonia gases may be formed in fires involving ammonium sulfate (10-12).
